The invention vgenerally'V relates to chart displayingdevices` and while adapted for signed foriuse in connection-with monotype machines in the kuse of which? operators are called upon to change pica ems andpoints (printers measure) yinto monotype keyboard measure and seeks to `provide astructure and a mounting. therefor in convenient positionr lupon the iiionotype'machine whereby the nec-- -essa'ry individual scales arekept ,directly before the-operator so that suchv changes may be made quicklyl and conveniently and with l very little, if any,fchance for error.

fIn its more detailed naturey the invention resides inthe provision of a casing having a longitudinal window, means for movably mountinga chart within the .casing torenable display ofselected` portions only` of thefchart,

` o'and novel-brackets in which the casing is removably lmounted andvvhich are shaped to present.' the displayed portionrof the chart in: e the' most convenient relation to the liney of vision of the operator.

'When e'mplgoyingjmy chart holder asabove described,.thes'crevvs 3 ser-vento secure to posiwhich are in the nature of metal strips bent Ushaped as at 6 to form holder receiving brackets,see Fi ures 3 and 4. From these figures, it Will e observed that the bifurcated ears of the brackets and the main body or U-shaped portions bear angled relation so that whenthe ears are secured in horizontal positionas illustrated in Figure4 of the drawings, the body portions of the brackets will extend forwardlyand downwardly so that the chart display face of the holder will be presentedsubstantially at right angles to the line of vision of an operator of the monotype machine on Whichthe holder is mounted.

' The holder: roper is preferably bent up from a single s eet ofmetal to providea bottom 7 ,f rear and front sides 8 and 9 respectively, and inwardlydirected top flanges 10 which j terminate short of the longitudinal center at thetop face of the holder to provide a longitudinal window opening 11. In

`practice this window opening is protected by a transparent sheet 12.

I provide a chart mounting unit which is preferably Vmountable and removable as a unit with respect to said holder casing. The

vmounting unit comprises end blocks 13 of a size for snugly fitting Within the ends ofthe casing and each of which is provided with three bearing bores 14 adapted to receive two outer chart shafts 15 and an intermediate driver shaft 16. v Each of the shafts 15 and 16 carries a gear 17, the gears beingintermeshed so that when the driver shaft 16 is rotated, the chart shafts 15 will v be caused to rotate in like direction. The gears may be provided in duplicate sets at the respective 'ends of the shafts adjacent kthe blocks 13 or at one end only as desired.y

Slip-over end caps 18 are provided to snugly encase theopen ends of the holder casing and one of said capsk is apertured to accommodate an extension 19 ofthefdriver shaft 16, said extension being equipped with a turning. knob 2O so that the driver shaft may be rotated from without the casing.

f Each chart shaft is equipped with a longitudinal slot 21 in which an end 22 of a chart 23 issecured as at24. In this manner the portion of the chart to be displayed through the window opening 11 is stretched across and over 4the top faces of the shafts 15, the

displayed face being varied at will by rotating the knob 20 to causey the respective ends of the chart to wind onto one shaft 15 and oil' the other shaft 15 according to the dif observed that the chart 23 is provided with horizontallines 25 dividing it into a pluralityof set size spaces 26, each of which is rection of rotation of said knob. By reference to Figure 9 of the drawings, it will be equivalent in width to the width of the window opening 1K1 so thatno more than a single Lholder, inrcouverting pica ems and (printers measure) into monotype key card occasion errors.

measures should be obvious. Under the usual practice cumbersome charts or tables have printed on opposite faces thereof the necessary information `for converting the types.

Obviously these charts are diiicult to handle, become soiled and broken, and make it very easy for an operator to take readings from other `than the proper set spaces and thus In my improved` chart holder. onlyk the correct set space is displayed and thus the chances for the operator to err are greatly reduced if not entirely eliminated. Furthermore, my improved holder positions the chart in such a convenientfmanner that -the type conversions may be made with a minimum of effort and expenditure of time. In order to change the set space displayed ythrough the Windowopening 11, it 1s only necessary to turn the knob 20 in the proper direction. The chart as a Whole is readily removable from the U-shaped mounting brackets and in order to remove the mounting unit to change achart or otherwise inspect or repair the same, it is only necessary to grasp the end cap adjacent the knob 2O andpull the same longitudinally off the end of the holder.V By thus removing the right hand cap, the mounting unit disclosed in detail in Figures 5 and 6 may be Withdrawn bodily from the holder.

By formingthe holder in thevmanner illustrated in Figures 2 and 3 of thedrawings, a certain resiliency is imparted to the holder .body by reason of the separation of the yflanges 10 thus facilitating the snug removable reception of the mounting blocks 13. Y y

It is of course to be understood that ythe details of structure and arrangements of parts may be variously changed and modified without departing from the spirit and scope of my invention. f
